“…The whole glow peak method is also usually used for the analysis of an isolated TL glow peak. The related parameters can be estimated using the following Equation (16) for the general-order kinetics [216,218,219] ln 11for the case of first and second-order kinetics. Reproduced with permission.…”

“…To this end, two methods, including T m -T stop (T m : the temperature at the maximum of TL glow peak) partial cleaning and T m -dose, are usually adopted. [215][216][217][218][219][220][221] With regard to T m -T stop partial cleaning method, the preirradiated material is partially heated from room temperature up to a temperature T stop at a linear rate (T stop corresponds to a point on the low temperature tail of a TL peak). After being cooled down to room temperature, the material is reheated to collect the complete TL peak, of which the position T m also can be obtained.…”

“…The observation that the position of TL peak is independent of irradiation dose signifies that the trap follows first-order kinetics, whereas that of a second-order or non-first-order shows shift toward lower temperature with irradiation dose. [215][216][217][218][219] To perform a kinetic analysis for a TL glow peak, six methods, including the peak shape, curve fitting, whole glow peak, initial rise, variable heat rate, and isothermal decay, have been proposed.…”

Optically stimulated luminescence (OSL) materials, enabling energy storage by capturing of charge carriers and then the energy conversion to light via photostimulation, can find many advanced applications in various fields, spanning from radiation dosimetry, optical data storage and security, environmental monitoring, biomedicine, clinical diagnostic, to archaeology and geology. At present, there are some blocks, including the development of nanocrystallization approaches, the tailoring of optical transitions, the control of trap distribution, and the understanding of OSL mechanisms, on the road to the exploration of OSL materials. This review gives an overview of the design, preparation, characterization, optimization, application, mechanism, and prospect of OSL materials. A short introduction of the fundamental principle and history of OSL materials is presented, followed by a summary of preparation and design methods, and a survey of OSL materials reported to date. The trap engineering, mechanism, and study methodologies of OSL are summarized, after which the widespread applications of OSL materials, in traditional and newly emerging fields, are reviewed. Finally, the merits and drawbacks of the OSL materials according to the relevant reports currently available are examined. The challenges and outlooks are highlighted and discussed in terms of five important aspects that merit future research.

The current study presents rhyolite as a novel and promising natural thermoluminescence emission (TL) material. The work focused on enhancing the TL sensitivity of rhyolite via optimization of the processing conditions: annealing and pre-dose effect. The glow curves of irradiated rhyolite sample showed a single peak of about 110 C at 5 C sec-1 heating rate. Sensitization was performed following Fleming's sensitization technique. It was found that applying 1 kGy pre-dose irradiation, followed by thermal activation at 550 C for 1 h, and cooling in air at room temperature were the optimum conditions for TL sensitivity improvement of this 110 C glow peak. Both nonsensitized and sensitized rhyolite have linear behaviour in the range 5-1500 Gy. The obtained results present rhyolite as a material for potential dosimetry applications.
